It was time to do front brakes on my 94 F150 Lightning. I wanted to get the EBC slotted rotors, but they were on permanent back order. So I ordered the Summit drilled and slotted rotors and EBC green brake pads. The thing will throw you though the front windshield it stops so good but whenever you just lightly press on the pedal, it bounces up and down and shimmeys. Now Ive rebuilt the whole front end with poly bushings and new ball joints. Has anyone experienced this before?
